Okay, i recently bought a new motherboard and processor, and i'ts all working. So i boot it up and install Windows 7 Home Premium (service Package 1) via a USB on one of my hard drives and it works! The problem is my other hard drive which is my main on my old PC, whenever i plug it in the system wouldn't get past starting windows. I think the cause is the old windows 7 OS installed on that drive, i want to possibly salvage my files so if anyone has a solution, I'll gladly welcome it!
